We provide a unifying approach which links results on algebraic actions by Lind and Schmidt, Chung Li, topological result Meyerovitch that relates entropy to the set of asymptotic pairs. In order do this we introduce series Markovian properties and, under assumption they are satisfied, prove several relate pairs (the homoclinic group in case). As new applications our method, give characterizati...

Problems related to the left ventricular outflow tract are not always amenable to conven— tional surgical metiuxis. and in some cases may be solved with the creation of a double ouclet left ventricle, using a composite rigid pyrolitc lcÍt ventricular apex outlet prosthcsis and a fabric valve-containing conduit. The prilnary indicacion for apico—aortic conduirs is severe left ventricular outlet ...

A 66 year old lady with history of hypertension, diabetes presented with advanced HF. She was diagnosed to have carcinoma breast in the year 2006 and had undergone lumpectomy followed by chemotherapy and radiotherapy. She presented with severe LV dysfunction with LV ejection fraction(LVEF) of 35% (NYHA IV) with left bundle branch block (LBBB). Despite optimal medical therapy she was admitted tw...

in this paper among many other things we prove that the topological left amenability and left amenability of a weighted hypergroup (k, ?) are equivalent. for a normal subgroup h of k, we define a weight function ?? on kih and obtain connection between left amenability of (k, ?) and (k|h, ??). let h be a compact subhypergroup of k. we define the weight function on k||h and obtain connection betw...

Consider a measure-preserving action Γ y (X,μ) of a countable group Γ and a measurable cocycle α : X × Γ → Aut(Y ) with countable image, where (X,μ) is a standard Lebesgue space and (Y, ν) is any probability space. We prove that if the Koopman representation associated to the action Γ y X is non-amenable, then there does not exist a countable-to-one Borel homomorphism from the orbit equivalence...

Abstract We give a short geometric proof of result Soardi and Woess Salvatori that quasitransitive graph is amenable if only its automorphism group unimodular. also strengthen one direction by showing compactly generated totally disconnected locally compact admits proper Lipschitz action on bounded degree then pass via the notion amenability group, which has previously been studied second autho...

Iliac vein compression syndrome is a condition involving external compression of the left common iliac vein by the right iliac artery, which was first described in the 1850s. It predominates in females typically between the third and fourth decade of life and has been associated with thrombophilias. Importantly, the syndrome is amenable to endovascular treatment. Here, we describe a case of a y...
